In another day of drama in President Donald Trump's White House, a gap in cybersecurity came to light.

An "email prankster" from the UK tricked senior White House officials and one of Trump's sons into engaging in sensitive exchanges by masquerading as members of the Trump team, CNN reported Monday. Victims of the deception included Eric Trump, Homeland Security Adviser Tom Bossert and former White House Communications Director Anthony Scaramucci, or "the Mooch." Scaramucci was booted from his job Monday just 10 days after he started.

In one incident described by CNN, Bossert, convinced the "prankster" was Trump senior adviser Jared Kushner, gave out his personal email address.

The impostor also pretended to be former White House Chief of Staff Reince Priebus and wrote to Scaramucci the day after Priebus was given the sack last week. Scaramucci, believing he was talking to the real Priebus, responded -- twice. He also replied to an email sent by the impostor posing as Ambassador to Russia-designate Jon Huntsman.
